CAN-SOLDERING MACHINE.

SPECXFICATION forming part of Letters Patent No. 399,020, dated March 5, 1889.

Application tiled January Z2, 1889. Serial No. 297.191. (llo model.)

To CLZ whom, it may concern:

Be it known that I, JoHN M. Connnnr, a citizen of the United States, residing at ManA tua, Gloucester county, New Jersey, have in- Vented certain new and useful Improvements in IvlachinernsT for Soldering the Tops of Tin Cans, of which the following is a full, clear, and exact specification.

My invention relates to machines for soldering' the tops upon sheet-metal cans, and especially to that class in which revolving soldering-irons are employed; and myinvention consists of a head for such machines embodying a series oi vertical spindles having pinions driven Jfrom a single revolving gear and carrying soldering-irons, and otherwise constructed, as fully set forth hereinafter, and as illustrated in tho accompanying dra u'- ings, in whichm Figure l is a plan view of a soldering-head embodying' my improvements. Fig. 2 is a sectional elevation of the said head. Fig. 3 is a plan illustrating a modification ot the driving-gear.

The head A may be a box, case, or frame of any suitable form and construction to support a series of spindles, l, to each of which at the lower end is secured a soldering-iron, 2, provided at its lower end with an annular soldering-ring, As shown, the. head is in the form of a case having a cylindrical rim or body, -projecting above a i'lat top, 5, to form an annular guide, G, and projecting' beloT a flat bottom orpartition, 8, to form a de.- pendent annular' lange, 9. Each spindle l passes through an opening in the top 5, and carries a pinion, lO, and all the spindles are arranged in a circle, so that all ot" the pinions 10 Will gear with the teeth of a deep annular' rack or gear-wheel, l2, which lies upon the top 5 and is maintained in position thereon by the guide 6. Each of the irons 2 passes through an opening, 13, in the bottoni 8, projecting to such an extent as to be guided by said bottom, Whatever may be the height to which the iron is raised. The irons are heated in any7 suitable manner common to this class ot apparatus, as by gas-jets, &c.,which are not shown, as they constitute no part of my present invention, and the annular gear-wheel l2 is driven from any suitable source of power and through any suitable mechanism, and as it revolves it imparts motion to all oi pinions 1G and the irons connected therewith. One mode of driving the Wheel l2 is illustrated,

the same consisting' of a guide-Wheel, 13, upon a shaft, 14, turning in a stationary support and provided with a grooved pulley, l5, receiving a driving-belt, 1G.

It Will be noted that the driving-Wheel l2 is much deeper than the pinions l0, and that the shafts and irons are so supported and suspended in the head as to be capable of a vertical movement. This permits the head to be lowered to bring the irons in contact with a series of cans, (shown in dotted lines) and also permits each iron to accommodate itselil to the height of the can below it without the pinions 10 being disengaged from gear with the Wheel. By this arrangement ot deep driving-gear and iron supportingshatts provided with pinions and capable of vertical movements independent of the driving-gear it is possible to move the entire head vertically to bring the irons on the cans, While t-he irons adjust themselves to the inequalities in the heights ot the cans.

By the use of a single driving-Wheel gearingwith a series of pinions each connected with one of the ironsl am enabled to rotate all the irons together, either continuously in one direction or to impart a reciprocating rotai'jfY motion thereto from a single d Living-shaft.

The driving-Wheel l2 may be in the form oi an ordinary toothed wheel instead ot being annular'. ln suoli case, however, it will be arranged Within `the circle ot pinions l0, as shown in Fig. 3.

In that class of machines in which the head is to remain fixed it will not, ot course, be necessary in all cases to provide a driver-wheel of greater depth than the pinion's, and only suffi cient Vertical movement or play ot the spindles and irons need be permitted to enable the irons to accommodate themselves to inequalities in the cans.

By extending the iiangc 9 below the bottom 8 I form a guard inclosing the lower end of the irons, which protects them from air-cnn ren ts and tends to prevent their rapid cooling.

IOO

XVithOut limiting myself to the precise construction and arrangements of parts shown, I claim- 1. A head for a can-soldering maohine,'con sisting of a case or frame,a series of spindles supported therein and provided with soldering-irons and pinions, and a driving-wheel gearing with all the said pinions, substantially as set forth.

2. The combination, in a head of a ean-sol-.

4. The combination, in a head of a can-soldering machine, of a case supportinga series 2 5 of `vertical spindles, a series of solderingirons carried by the spindles, the case eX- tending below the irons, and pinions upon the spindles gearing with the driving-wheel,

substantially as set forth. 3o

5. The combination of a case provided with a perforated top and bottom, a series of Vertical spindles extending' through the perforations in the top and each provided With a pinion at its upper end gearing with a driving- 35 wheel, and a series of soldering-'irons carried by the spindles and each extending through one of the perforations in the bottom of the case, substantially as set forth.

In testimony whereof I have signed my name 4o to this specification in the presence of two subscribing witnesses.
